Disp fx of distal phalanx of finger, subs for fx w nonunion

This code signifies a fracture of the furthest bone in a finger other than the thumb, where the broken bone fragments are no longer aligned. Crucially, this specific code indicates that the fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care related to this ongoing issue.

This code is appropriate for subsequent encounters when a patient is being treated for a previously diagnosed displaced distal phalanx fracture of a finger (excluding the thumb) that has not united. This includes visits for ongoing management, evaluation of nonunion, or planning for further intervention.

• Ensure documentation clearly states "nonunion" and "displaced" for the distal phalanx of an "other finger."
• Verify laterality (left, right, or unspecified) is consistent with the patient's record.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
